A dual alloy turbine rotor (100) is provided and includes an integrally formed blade ring (102) and a disk (104). The blade ring (102) is made of a first alloy and includes a ring portion (108) and a plurality of airfoils (106) extending therefrom, where the ring portion (108) includes an inner surface (114), and each airfoil (106) includes an internal cavity (124) formed therein. The disk (104) is made of a second alloy and may have a beveled outer peripheral surface (118). The disk (104) is disposed within the ring portion (108) such that the disk outer peripheral surface (118) contacts at least a portion of the ring portion inner surface (114). Methods of manufacturing the turbine rotor are also provided.
